Lego walking dragline takes its first steps

I've been working on and off on this model for the past couple of years. Today marks the first time it has rotated under its own power (with only one of four motors powered, for now) and more importantly it took its first steps.
While this model is not an exact replica of a real machine, it follows the general arrangement of this type. My main goal is to build a functional model. Until today I was not sure whether it would walk, so I'm quite pleased with the results.

Man this is unbelievable!! Awesome!! The arm design is perfect, movements are perfect, thats a masterpiece

How did u work on it? simply trying or following a project? and in case of a project how did u do that?

As u can see im amazed by this model :D

@Ste3B I used pictures of real machines from a couple of books. It is not an exact replica of a real machine but rather my own engineering of such machine given the constrains of the Lego system and the properties of the material (ABS).

Very good! Now get yourself an NXT and get rid of that pesky power wire :).

@Mikemc The real machines are electrically powered via a long extension cord (typically 16000V), so the power cord is correct for the model!

Where do you get the motors, wires, rotation bearings, and other special equipment for these?

@dwegmull I know what you mean, I've felt that way too, about Lego and other stuff.

@dankerthanclanker Offensive language aside, this model is based on a real machine which weighs about 7000 tons. The real machine takes one minute per step. Most movies showing these machines are greatly accelerated...

@ApacheSenior The build was spread over two years. There were many false starts and frustrating moments...

@dankerthanclanker no sadly =(

Stunning work. Well done.
